摘要/Abstract

摘要： 为在缩短行车间隔时减小弓网系统磨损,对接触网导线温度场进行研究。利用软件COMSOL Multiphysics建立仿真模型,结合温度场实验结果验证了有效性。在不同行车间隔下对货、客运列车接触线温度场进行仿真计算。行车间隔越小,温度值越高且平衡越快。货运列车长期运行的行车间隔不能小于180 s,客运列车运营时速下不能小于160 s,试验时速下不能小于140 s。行车间隔一定时,速度越大温度值越低,电流越大温度值越高。稳定运行后,间隔内温度差值在不同速度下相似,而不同电流下变化较大。

Abstract: To reduce the wear of pantograph and catenary system while decreasing the headway, the temperature field of the contact wire is studied. A simulation model is established by using the COMSOL Multiphysics software. The effectiveness of the model is verified with temperature experiments. Temperature field of the contact wire of freight locomotive and passenger locomotive in different intervals is studied by simulation. The smaller the headway of trains, the higher the temperature value, and the shorter the balance process. Under the constraint of temperature field, the headway of freight locomotive couldn't be less than 180s under long term operation. The interval of passenger locomotive couldn't less than 160s under operating speed and 140s under experiment speed. When the headway of trains is constant, the steady state temperature is lower at larger speeds. While steady state temperature is higher in larger currents. The temperature difference in one interval is similar under different speeds and large in different currents in stable operation stage.

Key words: headway of trains, contact wire, temperature field simulation, electrical sliding contact
